Persons engaged in product research and development often have a need to express their ideas and concepts to others. Heretofore, such persons have utilized elaborate graphical illustrations, charts, technical documentation and reports, circuit diagrams and the like to present their ideas to others. When a new product is in existence and available for demonstration, innovators have often demonstrated the product and its operation. However, if the product is not in existence or available at the time of the presentation, or if a products physical characteristics, complexity or functional properties render it unsuitable for demonstration, adequate communication of the ideas and concepts embodied in the product is not always a simple matter.

It is an object of the present invention to provide a dynamic pictorial display apparatus wherein illustrations or other graphical representations ofa device may be dynamically displayed by optical illusions whereby the illustration operates to display characteristics similar to the device depicted in the illustration.

It is another object of the present invention to provide display apparatus wherein illustrations of electrical devices contain hidden electronics operable to create an appearance that the illustration operates in a predetermined manner.

It is another object of the present invention to provide dynamic display apparatus for dynamically displaying illustrations of devices utilizing principles of optical illustration to present an apparently threedimensional, operational illustration of the device.

In accordance with the present invention, a housing is provided having support means for supporting photographs or other two-dimensional illustrations for threedimensional objects. The illustrations comprise laminated cards containing electronic circuitry such as touch entry switches, electrical indicators and the like. In addition, the illustration may include movable slides, flaps and the like which may be manipulated to present I an appearance of three-dimensional movement.

With reference to the drawings, particularly to FIGS.

1-3, there is shown a housing 20 having first and sec ond case portions 21, 22 supported by feet 23. For example, housing 21 may be constructed similar to an attache case or the like, which may be opened and supported as illustrated in FIG. 1. Conveniently, a handle 24 may be provided for carrying housing 20. Screen 25 is mounted in case 22 and may, preferably, comprise a planar translucent screen for a light box. Member 26 protrudes forwardly of screen 25 at the lower portion thereof to form a channel 27 below the forward lip of member 26. As will be more fully understood hereinafter, channel 27 is inclined rearwardly so that illustra tions supported within channel 27 are stacked against the inclined planar surface of screen 25. Strip contacts 28 are disposed on the lower surface of channel 27 and movable contacts 29 protrude from the lower surface of channel 27 and behind the front lip of member 26.

As will be made more fully understood hereinafter, cards 30 are laminated cards having a thickness of about inch and contain indicators and touchactivated switch devices for connection to driving circuitry within housing 20. Each card 30 includes a plurality of contacts (not shown in FIGS. 1-3), and a ground contact 31. In the apparatus illustrated in FIG. 3, switch device 29 comprises a contact having an inclined edge of 32. Switch device 29 protrudes through a slot in the lower portion of slot 27 and is biased upwardly by means not shown. Switch 29 provides ground connection to the forwardmost card 30 supported on channel 27. For example, if three cards are supported by channel 27 as illustrated in FIG. 3, contact 29 assumes the position illustrated in FIG. 3 by virtue of contact 31 of the forwardmost card contacting surface 32 of switch 29. With only two cards in channel 27, contact 29 is biased upwardly to the position illustrated by dashed lines 29a, and with only one card in channel 27 contact 29 is biased upwardly to the position illustrated by dashed lines 29b.

FIG. 4 illustrates a modification of the ground contact 33 wherein the contact is pivotaly supported at point 34 and biased upwardly by means not shown to contact the forwardmost card 30 in channel 27.

FIG. is a block circuit diagram of the driving circuitry for driving indicators and switches on cards 30. The driving circuit may, for example, by supported within case 22. A plurality of latch circuits, or flip-flops 40 each have an input connected to an individual contact 28a in channel 27. The outputs of latches 40 are connected through solid state switches 41 to contacts 28b, also disposed in channel 27. As will be more fully understood hereinafter, contacts 28a are connected to normally open touch entry switches hidden in cards 30 behind a pictorial illustration so that upon momentary closure of-a switch an associated latch is operated to impress a signal through a respective contact 28b to operate a lamp or other indicator in the card 30. Gate circuits 42 may be provided with a plurality of inputs 28a to selectably control selected ones of latches 40. Oscillator 43 may be provided to provide pulsating power instead of DC power output through a solid state switch 41 to a contact 28b. It is preferred that one of the latch circuits 40a control solid state switch 41a and driving circuit 44 to operate lamps 45 associated with the light box behind screen 25. Also, a delay circuit 42a may be connected between two terminals 28aand 28b. A battery pack, generally illustrated at 46 is connected to ground 47 which, in turn, is connected to the contacts 29 of the movable switches in channel 27. The battery pack is also connected to lamps 45, is tapped for connection to output'terminals 28b. As illustrated in FIG. 5, one of the taps is connected to driving circuit 48 for operating lamps or other indicators associated in the card. Preferably, an AC-DC converter 49 is provided for recharging the batteries of battery pack 46. Alternatively, direct AC operation of the circuitry may be utilized, particularly in fixed installation displays. Also, a ganged on-off switch 50 is provided to control power to the circuit.

The circuit illustrated in FIG. 5 is given as an example of a typical driving circuit and should not be construed as limiting the invention. The interconnections between switches and circuits, and between the circuits and indicators is accomplished by selectively connecting the switches and indicators in a particular card to respective contacts 28 for selective operation of various ones of latches 40. The latches, amplifiers and oscillators may be operated in sequence, or in parallel and in any desired logic configuration, depending upon the intended operation of a card 30. Further, several circuits may be interconnected by wiring terminals 280 and 28b together within card 30 for additional programming purposes, as will be more fully understood hereinafter.

FIGS. 6-8 show a two-dimensional, pictorial illustration 60 of a three-dimensional object in accordance with the presently preferred embodiment of the present invention. In FIG. 6, a two-dimensional photograph or other pictorial illustration 60 is attached to card 30. By way of example, illustration 60 may comprise a suitable photograph of a prototype electrical apparatus such as a keyboard display apparatus as illustrated in the illustration 60 appearing in FIG. 6. As shown particularly in FIG. 7, card 30 comprises a front card section 61 and a rear card section 62. As will be more fully understood hereinafter, sections 61 and 62 are attached together by suitable attachment means such as magnets mounted to each of the card sections so as to form laminated card 30 comprising the sections 61 and 62. Contact 31, adapted to mate with switch contact 29 of the housing illustrated in FIGS. 1-3, is mounted to the lower edge of section 61. In addition, spring loaded contacts 80 are mounted to the lower edge of section 61 and protrude therefrom to make electrical conncction with contact strips 28 in channel 27 of the housing.

As shown in FIG. 6, illustration 60 depicts a keyboard display apparatus having a plurality of keys 63, a screen 64, and a plurality of indicators 65. Located behind the illustration of certain of the keys is a plurality of touch actuated switches 66, 67, 68, 69 and 70. An additional touch entry switch 71 is located behind a remote portion of the illustration for purposes to be hereinafter explained. Switches 67-71 may, for example, comprise membrane switches mounted to card section 61. Such switches ordinarily comprise a pair of flexible conductive membranes in spaced relation which are capable of contacting by the application of a small pressure. Screen 64 is preferably a translucent screen mounted in the photograph 60. A plurality of a alphanumeric indicators 72 may be positioned behind screen 64. In addition, screen 64 may also include suitable alpha-numeric characters 64 so that when a lamp behind screen 64 is operated, the characters will be displayed on the screen. A suitable aperture 73 is provided in one portion of the illustration to expose a lamp or other suitable indicator 74. I

FIG. 8 is a plan'view of the rear face of card section 61 showing the electronics contained within card 30. As shown in FIG. 8, screen 64 is positioned over a suitable aperture 75 (FIG. 6). Screen 64 preferably includes suitable indicia 64 which may be viewed through the screen upon projection of light on the screen. Ground contacts 31 are connected by lead 76 to each of the electrical devices mounted on the rear surface 77 of card section 61. Thus, one side of touch entry membrane switches 66, 67, 68, 69, 70 and 71, and of indicators 72 and 74 are electrically connected to ground contacts 31. The opposite side of each switch and indicator is connected to separate ones of contacts 80 by suitable leads mounted to surface 77. In addition, several of the contacts 80 may be connected together by jumper leads or the like as illustrated at 78. A plurality of permanent magnets 79 are mounted to surface 77 in spaced relation allowing the electrical connections to be mounted therebetween. For example, magnets 79 may comprise a suitable rubberized magnetic material bonded to card portion 61 at suitable locations, and card portion 62 may be provided with similar matching magnetic portions so as to fixedly attach card portions 61 and 62 by the magnetic attraction between the various magnets. Contacts 80, as illustrated in FIG. 8, are preferably spring loaded contacts so as to make positive contact with strip contacts 28 in channel 27.

In the use of the card illustrated in FIGS. 6-8, the card segments 61 and 62 are attached together by suitable fastening means, such as the magnets 79 attached to the card segments, to form the completed card 30. Card 30 is thereafter placed in channel 27 of housing so that the illustration 60 may be viewed forward of the housing. Touch entry switches 66, 67, 68, 69, 70 and 71 are connected via individual connectors 80 and 28a to selected ones of latches 40, 40a of the circuit housed in housing 20. Likewise, the various indicators 72, 73 are connected by contacts 80 and 28b to the outputs of various amplifiers 41 of the circuit illustrated in FIG. 5. In the case of the card illustrated in FIGS. 6-8, screen 64 is exposed to screen through suitable apertures 75 in the rear of card 30.

Assuming that the device illustrated in photograph 60 is a keyboard display unit for use with a computer, and assuming further that an operator is desirous of explaining the operation of the keyboard display unit to others, the operator closes switch 50 to energize the circuitry to activate the card. At the start of his scenario, the operator may touch the region of illustration 60 depicting the toggle switch in the center of the illustration thereby actuating switch 66 behind the illustration of the toggle switch. Switch 66 is connected via selected contacts 80 and 28a to a latch or flip-flop (FIG. 5) in housing 22 to operate that latch to thereby operate the associated amplifier 41. Amplifier 41 provides an output signal via selected contacts 28b and 80 to operate lamp 74. The illumination of lamp 74 thus depicts the illusion that the device depicted in the photograph is ready to operate. Thereafter, the operator may selectively operate selected ones of switches 67-69 behind illustrations of keys 63 to actuate respective latches and amplifier to operate alpha-numeric indicators 72 so that an alpha-numeric message is illuminated onto screen 64. For example, by depressing the region of illustration 60 associated with the key T, a T is illuminated onto screen 64 by indicators 72. Thereafter, the operator may operate switch 70 located behind a depiction of another key, to operate latch 40a in FIG. 5 to operate lamps of the light box behind screen 25 in housing 22. The illumination of screen 25 is projected through screen 64 to permit viewing of indicia 64' to complete a predetermined message on the screen.

Assume that during the scenario the operator desires to explain various alternatives of construction of the proposed device. Assuming further that one such alternative is to provide a flashing indication instead of a steady state indication which the operator would explain to the audience would conserve power, the operator may show this alternative by operating hidden switch 71 to initiate operation of oscillator 43 (FIG. 5). Oscillator 43 is connected through selected contacts 28b and 80, jumper wire 78, and selected contacts and 28a to the input of latch 40a, thereby operating lamps 45 in a flashing mode. Obviously, other indicators may be flashed and interconnected in any desirable manner. The electronics associated with a particular card 30 may be turned off merely be operating an appropriate hidden switch and/or by removing the card from channel 27 to break the connection to the circuit shown in FIG. 5.

FIGS. 9-11 illustrate yet another embodiment of a card 30 for use with the apparatus illustrated in FIGS. 14. Card 30 includes card sections and 86, held together by means of magnets 79. Cavity 87 is formed in section 86 between the card portions to contain the electronics for operating the indicators and switches associated with two-dimensional illustration 88. Illustration 88 depicts a three-dimensional view of a computer console having a plurality of push buttons 89 and a plurality of indicators 90. Light emitting diodes or other suitable indicators are provided in suitable slots in illustration 88 for each indicator 90 shown therein. Also, touch entry switches 91 are positioned behind selected ones of push buttons 89 depicted in the illustration. Switches 91 and indicators 90 are connected to spring contacts 80 and to ground contacts 31 as heretofore described for connection to the circuitry shown in FIG. 5. Flap 92 is hingedly attached at 93 to illustration 88 and depicts a cover for the console. A suitable slot 94 is provided in illustration 88 so that slide 95 (FIG. 1 1) may be moved in the direction of arrow 96 to either of two positions. Slide 95 depicts a drawer containing electronics 97. Illustration 88 includes a representation of electronics 98 beneath flap 92 so that when flap 92 is moved to the position shown in FIG. 11, electronics 98 may be viewed on illustration 88. The electronic circuits 98 depicted in illustration 88 beneath flap 92, may for example, be illustrations of plug-in circuit modules, and slide 99 depicting the absence of a circuit module may be provided to selectively cover a depiction of one such module to present the illusion of removal of that module.

As an example of the use of the card illustrated in FIGS. 9-11, the card is positioned in channel 27 of the housing 20 so that contacts 80 make electrical connection with contacts 28 and contacts 31 make connection with contacts 29. The operator may operate selected indicators in slots 90 by actuating selected ones of switches 91 positioned behind keys 89 of the illustration 88. Assuming that the operator desires to explain the servicing of the unit depicted in illustration 88, he may revolve flap 92 about hinge 93 in the direction of arrow 100 from the position illustrated in FIG. 9 wherein flap 92 lies flat on illustration 88 in one position to the position illustrated in FIG. 11 wherein flap 92 lies flat on illustration 88 in a second position. Slide 95 may then be pulled to the. left as illustrated in FIG. 1 1 to expose the illustration of the electronic drawer 97 shown in FIG. 11. Assuming the operator desires to show the manner of operation of the plug-in modules 98 illustrated in FIG. 11, he may, by hiding an actual plug-in unit in his hand, maneuver slide 99 over the depiction of the respective plug-in module to block the depiction from view, and thereafter show the actual plug-in module previously hidden in his hand to those viewing the scenario. Thus, the audience viewing the scenario will see a depiction of the unit in operation as it would appear if the unit had actually been present.

The present invention thus provides apparatus for presenting a dynamic pictorial display of apparatus, and particularly electronic apparatus, utilizing optical illusions to explain the mode of operation of the device shown in the photograph. Electronic devices, including indicators and membrane switches are utilized in connection with a standard logic circuit to aid in the illusion. If desired, rear projection apparatus may be provided within housing 22 for projecting still or motion pictures on the screen of a card, thereby providing a predetermined sequence of a plurality of display images.

One feature of the invention resides in the fact that each card is programmed for operation in accordance with the wiring of the card, and the logic is established by selection wiring to standard contact configuration so that standard electronics within the housing is utilized for each card. Indicators on the card can be controlled to delayed operation, flashing conditions and dim and bright operations in addition to on/off operation, as determined by the logic circuitry and switching arrangements.

Another feature of the present invention resides in the fact that several cards may be placed on a single support and only the forwardmost card is electrically connected to the circuitry in the housing for operation. Preferably, magnets (not shown) are provided at the lower edge of each card for magnetic coupling to magnets in channel 27 of the housing to hold the cards 30 in proper electrical registration during presentation. A card may be removed merely by rotating the card forward to break the magnetic attraction between the magnet in the card and the magnet in the housing to thereby remove the card and electrically connect the next card behind the first card to the electronics in the housing.

Another feature of the present invention resides in the provision of movable portions on the illustration, such as flaps and slides and the like, to convey threedimensional movement on a two-dimensional illustration.'Obviously, the movable portions can also be associated with switches in the card to control a predetermined electrical response. Also, audible indicators, loudspeakers and the like, may be incorporated to present a predetermined, or recorded, audio message or indication.

The present invention thus provides apparatus enabling an operator to present a dynamic illustration of the operation of electronic apparatus, even though such apparatus is not in existence and is only presented pictorially. The apparatus provides a dynamic display which, through the use of optical illusions, slides, flaps, light boxes, and rear projection pictures, present an impression that the device depicted in the illustration is in operation. With a dynamic display device in accordance with the present invention, an operator can explain new products to prospective manufacturers and purchasers in a manner not heretofore capable through the use of graphical presentations, charts and the like.
